Almost a month into Canada's waltz with legal weed, a new poll suggests Canadians are divided when it comes to the age to buy and consume marijuana.

The federal government set the minimum age for recreational cannabis at 18, but left it up to the provinces and territories to decide if it should be higher. At the moment, it's 19 in most provinces and territories, while Alberta and Quebec have set it at 18.

A new survey from the Angus Reid Institute, however, found that while 27 per cent of respondents agree that the minimum age should be 18, a similar number of correspondents (26 per cent) want it to be 21. Some want it even higher than that — 13 per cent said the legal age should be older than 25.

The listing of Aurora Cannabis (TSX:ACB)(NYSE:ACB) on Wall Street last October was merely preparation for something grand. The company wasn’t expecting share prices to astronomically rise, as it wasn’t a typical IPO roadshow. However, it gives institutional investors the option of investing in the Canadian or American stock exchanges.

Aurora is after a bigger slice of the legal cannabis pie whose estimated value is about USD $5 billion. However, recent events showed a different story versus the original script envisioned by marijuana companies. Instead of soaring after October 17, the market sell-off drove the cannabis stocks lower. Fortunately, November is exhibiting hope.

If you want to imagine the future of marijuana in the 2020s, picture a 3-D printer. 

Maybe it's in a kiosk at your local legal recreational dispensary; maybe, if you're a particular fan of greenery, it's in your home. Either way, it's pre-loaded with concentrated liquid forms of all  cannabinoids, the different kinds of molecules that make up marijuana. 

The machine has CBD for healing, CBN for sleepiness, THC for the giddy, giggly high; plus a ton of essential oils called terpenes, which generally provide every other subtle effect you've ever noticed with weed.

The news for marijuana penny stocks can't get much better.

Over the last two weeks, national and state governments in North America have dealt a wave of final blows to marijuana prohibition, paving the way for full legalization – and tremendous profits.

On Oct. 31, Mexico's Supreme Court struck down the nation's marijuana prohibition law. Shortly afterwards, Mexico's incoming government announced plans to pursue full legalization.

Less than a week later, three American states took huge leaps toward full legalization during the midterm elections. Both Missouri and Utah voted to allow medical marijuana use, while Michigan voted for full recreational legalization.

That's not even mentioning Canada's nationwide legalization on Oct. 17.

The prescription of cannabis for medical purposes – without the need for a special permission – was legalized in Germany in March 2017. Since then, a wave of approvals for medical cannabis has swept across Europe, with many countries following in Germany’s footsteps.

Pot stocks have been trading at very high multiples to sales for a long time and even a lack of profitability has done little to curb excitement in the industry. However, we’re starting to see signs of that changing.

This week, many marijuana companies are reporting their earnings, and the results have been very telling, as investors have not been buying up stocks that have simply achieved strong sales growth.

On Tuesday, Cronos Group (TSX:CRON)(NASDAQ:CRON) released its quarterly results, which showed sales rising by 186% year over year. However, the company reported a net loss of over US$7 million, which was a big drop off from the profit it achieved a year ago.

The supply shortages that have plagued many provinces in the first month of legal cannabis will likely persist for years, industry insiders say.

Provinces including British Columbia, Alberta, Manitoba, Saskatchewan, Quebec, Nova Scotia and New Brunswick have all reported varying degrees of shortages.

It could be a $146 billion sector in less than a decade, but for investors whose interest has been piqued by cannabis stocks, there is still no reason to rush into the publicly traded companies.

Sproutly Canada, Inc.’s move to establish a joint venture with Global Canna Labs Limited, the Caribbean’s largest medical cannabis producer, allows the Vancouver-based company to advance its vision and expand its business outside Canada.

The companies have signed a letter of intent (LOI) to establish a joint venture that will focus on developing, producing, distributing, marketing and selling cannabis-infused beverages, edibles and topical products derived from Sproutly’s fully licensed APP Technology.

“The signing of the definitive agreement and establishment of the joint venture is expected to occur in January 2019,” notes a statement from Sproutly.

You’ve heard of Big Pharma and Big Tobacco. How about Big Marijuana?

The drug’s growing legalization is raising concerns among small-scale marijuana farmers and retailers that the corporatization of weed may be right around the corner.

For example, earlier this year NASDAQ became the first major U.S. stock exchange to list shares of a marijuana production company. And in August, Corona-maker Constellation Brands shocked Wall Street by making a US$3.8 billion investment in a Canadian marijuana producer, sparking a bull market in marijuana stocks industry-wide. Even Coca-Cola is exploring opportunities to get involved.
